Of Freedom, Markets, and the Future of India

Markets Work, Incentives Matter

The two broadest generalizations one arrives at from a study of economics are that markets work and that incentives matter. People respond to incentives because that is at the core of what it means to be rational. To the extent that humans are rational, their behavior is predictably in the direction that existing incentives point to. Trade between humans is rational because both parties in any voluntary trade benefit. The abstract mechanism which enables trade is called the market. Markets work in the sense that they maximize the gains from trade among an arbitrary number of entities. There are other methods of enforcing trade among people, such as the command and control mechanism often employed by communist governments. But they are at a distinct disadvantage relative to the market because the latter is based on the premise that rational actors respond to incentives.

The Fabulous $10 Indian Government Laptop

“Everything reminds Milton of the money supply. Well, everything reminds me of sex, but I keep it out of the paper,” wrote Nobel prize-winning economist Robert Solow in 1966 about Milton Friedman, another Nobel laureate economist, the father of monetarism. 🙂

Everything reminds me of India’s failed education system — and by extension — the stupidity of the government policymakers, bureaucrats and politicians included. Unlike Bob Solow, however, I cannot keep it out of my posts.

Food prices

“When you start getting wealth, you start demanding better nutrition and better food, and so demand is high, and that causes the price to go up.” That’s what George W Bush said in a press conference on May 2nd. The NY Times reports:

In response to the president’s remarks, a ranking official in the commerce ministry, Jairam Ramesh, told the Press Trust of India, “George Bush has never been known for his knowledge of economics,” and the remarks proved again how “comprehensively wrong” he is.

Global Poverty and the Cell Phone

A magazine article in the New York Times of April 13th has the rather mistaken and misleading title “Can the Cell Phone End Global Poverty?” (Hat tip: Abhishek Sarda). The article title is misleading because it doesn’t even remotely attempt to answer that question. It is instead about what is called a “human-behavior researcher” or “user anthropologist,” in this case someone who works for Nokia and essentially tries to figure out how people actually use their phones and thus how phone companies should design phones for greater usability.

Dr Adam Smith, I presume

The other day I sat down to have a conversation with the spirit of Dr Adam Smith (1723-1790), professor of moral philosophy at the University of Glasgow and Fellow of the Royal Society of London and Edinburgh. A stellar observer of the human condition, his book, “An Inquiry into the Nature and Causes of the Wealth of Nations,” was published in the same year, 1776, as the Declaration of Independence of the United States. Opinion is divided on which of the two events is of greater importance for the subsequent evolution of the world we live in.

What follows is a rough transcript of our talk.

An economics moment

This is a personal post. Not exactly what I had for breakfast type of post but close.

I clearly remember the moment when a light went off in my head. Brian Wright was teaching and we were talking about EV and CV. Equivalent variation and compensating variation, and the related concepts of “willingness to pay” and “willingness to accept.” As I had come to economics rather late in life, I had had the opportunity to figure out some of the basic concepts in my head. But I did not have the vocabulary to fully express the ideas. So when I got the vocabulary, it was an “aha” moment.

I remember Brian posing the question: so PG&E (the local gas and electricity utility company) is going to string up high-tension cables above your backyard. You know that that increases health risks. In economics terms, negative externalities accompany this action. That raises two questions.

  • How much are you willing to pay to stop PG&E from doing so?
  • And how much are you willing to accept to allow PG&E to do so?

Note that in the former case, the assumption is that PG&E have the right to string high-tension cables over your backyard and you wish to stop them; in the latter case, you have the right and can disallow PG&E from stringing wires across your backyard. It’s a matter of who owns the rights.

The willingness to pay is bounded by how deep your pockets are but the willingness to accept is open-ended. If PG&E owns the rights,then most likely you are out of luck because you will not be able to pay them enough to deter them from going ahead. If you own the rights, then you can make a pretty neat pile of cash by holding out.

Ronald Coase showed that regardless of who owns the property rights, if there are no transaction costs, then bargaining among the parties is sufficient for the discovery of the economically efficient amount of pollution.

Sometimes I wonder. I wonder if we would continue to have the kind of problems such as Nandigram if basic economics principles were better appreciated by a large percentage of the population. I think a lot of coercion and violence could be avoided. But perhaps I place too much faith in rationality.

Education Spending

This is a follow up to the post on Indian spending on education abroad.

The actual spending may not be $13 billion annually but the argument does not change even if the figure was much lower. What matters is that it is indicative of a problem and we should be concerned about it. It should be noted that this spending is an outflow of resources. That in itself is not a bad thing, however. We need to ask if this is a net outflow in the education sector. That is, what is difference between the inflow and outflow.

Knowing Basic Microeconomics — Part 2

This is a follow up to the previous post on Knowing Basic Microeconomics where I had claimed that micro theory is essentially codified common sense and that it is never too late to learn a bit of microeconomics. Many people have written to me (and some commented on the post) that they would like references to some work that makes micro theory accessible to the lay person.

I am not familiar with what is available and therefore I am not qualified to answer that question. I have read a few non-academic books on economics but they are the type that attempt to address the concerns that are usually macro in nature. I find macroeconomics only mildly interesting. But macro stuff (dare I call it nonsense?) is what you normally read in the popular press — stuff about the business cycles, interest rates, unemployment, inflation, etc. Pundits on TV and newspapers are always going on about GDP growth rates and how the developing economies are doing and what will happen in the year 2030 or some such remote date. I find it uninteresting because most of those stories are “just so” stories and everyone has his favorite.

Of Kakistocracies, Principals, and Agents

Enclaves of Private Luxury

Just off the expressway from Mumbai, on the road leading into Pune, you see huge billboards advertising new housing developments with fancy names like “Whispering Pines” and “Orchard View” crowding each other, promising idyllic lifestyles of lavish comfort. They convey very urgently a palpable sense of how rapidly the market for private luxury dwelling is blossoming thanks to increased salaries and easy housing loans.

These billboards reflect the increased aspirations of the growing upper middle-class in India. Curiously, one set spoke to a deeper and disturbing reality. One billboard said, “Power Cuts? No problem. We have 24-hour generator backup.” Another one down the road said, “Water Shortage? Have a shower. We have our own water supply.”

Knowing Basic Microeconomics

Smart people think alike. Or at least they reach similar conclusions. Take Charlie Munger and me. We reached the same conclusion about the importance of microeconomics. Seriously though, I think it is a crying shame that people in general don’t have even a nodding acquaintance with the basic principles of microeconomic theory.
